On Windows, there’s an ever-growing number of utilities designed for cleaning up your directories and thereby maximizing hard drive space. Some even intend on optimizing memory and processing speeds along the way.

While being advertised as enhancements to your PC’s performance, the reality is that some of these programs are more likely to eat away at your computer speeds. Alternatively, some of these apps even charge money after revealing an extensive list of hindrances on your PC’s efficiency.
